The drills really aren't that bad, assuming that the dentist doesn't botch it. No new technology can be expected to solve poor technique or accidents.
Actually, the way I understood this is that plasma is used to disinfect the dentin, instead of mechanically drilling away the infected part. So there is less potential for mechanical damage as well. Some drilling is probably necessary to remove the mechanically decayed part, but there is less need to remove extra layers just in case.
One alternative for a 64-bit system with low power consumption is MIPS. For example the Lemote netbook that RMS uses has an 800 MHz MIPS64 called Loongson that consumes just a couple of watts maximum. I don't know much details, but apparently the CPU has proper floating point performance, unlike most ARM processors. While ARM systems do come with DSPs for media processing, MIPS could be more interesting for general computing.
Not just for teaching the core ideas, but to demonstrate that chemistry can be fun, and you get to play with fast computers. In fact, my lecturer in molecular modelling admitted that he got into the field partly because of the pretty pictures. I have also focused on the modelling aspects in my chemistry studies, mostly due to my past experience in computational physics.
I would like to note that my primary career is in teaching, and I have discussed the use of computers in science teaching with lots of experts. It is true that the core concepts and laboratory work are essential, but it is still a good idea to use some extra motivation for students with different interests.
PHP is a weakly typed language, so for any given operation, the interpreter will have to check the types of the operands and then figure out which operation(s) on the CPU to call to solve it. Also, as it's dynamic, the operand may not even exist yet.
I think Python has basically the same problem. Compiled.pyc files are actually bytecode, like Java. They save the time of the initial interpretation, but do not make the actual execution faster. Then there is also Psyco.
It also installs and runs on a N800, after all the internal hardware is almost the same as in the N810. It is likewise slow, actually looks and feels much like Fennec (what is the difference anyway?).
True, I have Gentoo running on both of my two ARMs (pun intended). But it's not really a distro issue anyway. The Linux kernel runs on more architectures than any other OS, and getting a distro to work is only a matter of time. And you can always install Linux from scratch.
Notice the lack of the word "support" above. I'm not that interested in support, I'm more interested in whether something works. For example, there's some kind of support relationship between my laptop and Windows XP, but I find that Linux works much better.
Well apparently it's an SoC, but they are likely using external IP for different areas of the chip. So some of it is cool. One thing--wasn't the problem with G5 it being too hot? Don't see why they would go back to that for something portable.
Apparently the CPU in iPad was designed by the former P. A. Semi designers. Before the Apple merger, they designed the Pwrficient, which was basically a G5 SoC, consuming a few watts at a GHz or two. An excellent processor on paper, but it was never available except on dev kits.
Here in Finland we have unlimited 3G data for 10 euro per month, and it doesn't exactly feel fucking awesome. Actually that is the lowest speed of 384/384 kbps, and for 30 a month you can get a few megs of downstream, though good luck getting the maximum in practice.
I have a Nokia N800, it's one of their earlier tablets with no keyboard. I have found the onscreen virtual keyboard surprisingly fast and practical, so I have little interest in handwriting recognition or other alternatives.
It probably helps that I know qwerty from over 20 years of use, so I can tap around the virtual version by a quick glance. For comparison, try typing on a regular keyboard with a single finger, it's not so bad if you think of the alternatives.
So far you couldn't use the GPU and you where only using a small part of the CPU processing power. Now imagine having this great multiprocessor architecture completely unlocked for you to program it. These are great news.
AFAIK, with Linux (or any other "Other OS") you can use the PPU and six SPUs. The seventh SPU is reserved for the hypervisor, so not a huge difference there. Some scientists are already using clusters of PS3 for their processing power.
I guess the typical problem with Linux on a PS3 is that only few programs are optimized for the SPUs. The PPU, on the other hand, is a regular PowerPC so there is already plenty of software for it.
So This hack will mean my linux install won't be crippled to only access half the memory?
AFAIK, you can already access the whole of the video memory, even though you cannot use the GPU. It is not usable as plain RAM, but you can use it as a fast swap device. This is actually an old Linux trick, but due to the fixed configuration it has been made a little easier on the PS3.
(I don't have a PS3, but I have played around with the same trick on regular x86 machines.)

PS3 Hacked?

· Score: 2, Interesting
If you buy a PS3 and use it as a computer or HTPC or whatever, they lose money on it.
So why did Sony enable the installation of Linux or other OSes on the non-slim version? Even without the GPU, it has turned out an incredibly powerful computer for some uses. Some research groups use a cluster of PS3s for scientific work, for example.
Perhaps you are looking at desktops and more expensive laptops. Most laptops I see still come with VGA, even though the display will be a digital one in most cases.
The idea of combining audio and video into one cable was a pretty fair one, though, especially considering that it reduces the mess of cables you'd see behind a TV, say, ten years ago.
DVI + sound is not such a bad idea. But HDMI gives you a fragile connector and a particularly bad kind of DRM in addition. As an encryption scheme it is a joke, and there are easier ways to rip a movie than the raw video stream.
If Nvidia had created a usable neutered (2D) OSS driver that Just Worked (TM) with their cards, a la ATI/IBM, then I'd still be suggesting their cards for Linux newbies like I did back in the Aughties. Instead, I've been suggesting IBM first, ATI next, and Nvidia only for experienced folk who need superior OpenGL cards.
I've never heard of IBM graphics cards. Do you mean Intel or something else? I personally recommend Intel graphics for Linux users, since the only drivers they make for Linux are opensource, with full 3D capabilities ("full" as in what the chip is capable of).
Incidentally, my most reliable Flash player is found on a Nokia N800, running Linux on ARM. Fortunately there are ways to download the video file in many cases.
Slashdot Mirror
This is bad. Slashdot used to be about computer science, now it is about consuming mindless entertainment.
Since "mete" is the verb behind the noun "meter" (as in voltmeter or parking meter), I suggest that the verb for laying fiber could be "fibe".
Not to mention that "wierd" weirds "weird".

There is even an app store for the N900, for those who'd rather part with their money than learn a little about open source.

Actually, 1337 is not particularly elite as it is a composite number. For true primal eliteness, use 31337 instead.

I believe the correct spelling is "hippocracy", if you mean a nation ruled by large semi-aquatic mammals.

Yet another reason people need to abandon 32-bit OSs. Seriously. What's the point of using half the power of your CPU?
I only have 32-bit hardware, you insensitive clod!
Perhaps you are looking at desktops and more expensive laptops. Most laptops I see still come with VGA, even though the display will be a digital one in most cases.
I think VGA is still the king when it comes to price/performance ratio.
Digital -> analog -> digital conversion costs money and degrades the signal.

DVI is fine. HDMI is a "super cable" version of DVI.
